Technical Field
The utility model relates to an underground pipeline settlement monitoring, in particular to laying device of underground pipeline settlement monitoring point.
Background
The underground pipeline is influenced by precipitation, construction, underground water level change and the like in the long-term operation process, and the soil body around the pipeline can generate uneven settlement change, so that the underground pipeline can also generate settlement of different degrees, and the safety of the underground pipeline is seriously influenced. Therefore, after the installation and construction of the underground pipeline are finished, the settlement change condition of the underground pipeline needs to be monitored periodically.
The settlement monitoring is needed to be carried out on the underground pipelines close to the periphery in the foundation pit excavation construction, the influence of the foundation pit construction on the pipeline settlement is mastered in time, effective safety measures are taken, and the safety of the peripheral pipelines in the construction is ensured.
There are generally two ways to monitor the settlement of underground pipelines: indirect monitoring points and direct monitoring points. The indirect monitoring point is a pipeline monitoring point which is formed by embedding a steel bar in a drill hole above or on the side of the pipeline and is equal to an earth surface monitoring point, and as the indirect monitoring point is not directly connected with the pipeline, the monitoring data cannot truly reflect the sedimentation state of the pipeline, and misguidance can be caused to later decision; the direct monitoring points are directly connected with the pipeline in a hoop mode, monitoring data can accurately reflect the real settlement state of the pipeline, but the existing arrangement method of the direct monitoring points is often damaged in the later backfilling construction process of the pipeline, and the safety monitoring of the pipeline in the later period is seriously influenced.
Disclosure of Invention
In view of the needs of practice, the utility model provides a laying device of pipeline settlement monitoring point, its simple installation, not influenced by later stage construction, convenient to use is reliable, raises the efficiency when carrying out pipeline settlement monitoring. The concrete technical scheme is, a laying device of pipeline settlement monitoring point, including monitoring point pre-buried device, earth's surface monitoring connecting rod, wherein monitoring point pre-buried device comprises staple bolt, fixation nut, locking pin axle, its characterized in that: a nut is welded and fixed in the middle of each hoop, the nut is matched with the earth surface monitoring connecting rod, the earth surface monitoring connecting rod is screwed in the nut, a locking pin shaft is arranged on the hoop, and the hoop is clamped on the outer surface of the underground pipeline and locked by the locking pin shaft.
The earth's surface monitoring connecting rod be the steel material, one end has the screw thread to with the nut phase-match on the monitoring point pre-buried device, the other end is smooth sphere, is convenient for place the levelling rod.
The beneficial effects of the utility model are that, monitoring point pre-buried device simple structure, preparation, installation and application are convenient, install pre-buried device during pipeline installation construction, do not receive later stage construction influence, subside the monitoring point and be difficult to receive destruction, can promote later stage pipeline settlement monitoring survival rate by a wide margin.
